Pollen count Centro 22 residents check each morning
The Centro 22 pollen count today is 37 (Low). The main driver is Ragweed, with weed pollen at 37 today. The full split is tree pollen 20, grass pollen 1, weed pollen 37. The sections below break that headline number down by plant, by day and by what the band means in practice. Pollen Atlas updated this count on Sunday, November 8, 2026.
A Low band on the Pollen Atlas index means the Total Pollen Index has stayed in the lower part of the 0–100 scale. Readings in this band are built from low individual category values rather than from one large spike, and the category split above matters more than the headline number: a low total can still contain one category, such as weed pollen or mold, reading noticeably higher than the rest, which is why the split is printed on every Centro 22 page.
Fall is ragweed season across most of the United States: ragweed plants release pollen from late summer into autumn, and weed pollen is typically the last major outdoor pollen category to fade as the weather cools. That pattern is why an autumn total is so often weed-led even when the headline number is low — tree and grass pollen have usually receded by then, leaving weed pollen, and on damp days mold, to make up most of what the index records.

Pollen by type in Centro 22
What is driving Centro 22’s pollen today
The shape of today’s 37 (Low) is set by weed pollen at 37 (Low on its own scale) — about 64% of the four category readings added together, 17 points clear of the next category, tree pollen at 20. A weed-led total is the classic late-year shape: tree and grass pollen have usually receded, leaving weed pollen — and on damp days mold — to make up most of what the index records. Weed pollen leading in November is the Italy calendar working as expected — November falls in the closing weeks of the country’s weed chapter.
Plant-level detail is not in today’s feed for Centro 22, so the drivers have to be read from the category split above — it shows how much of today’s total each category is actually carrying, and plant detail returns here automatically on any day the feed includes it.
Across the five-day window the Total Pollen Index runs from 16 to 40, changing band 1 time. Today’s 37 sits 10 points above the window’s average of 27.2 — a moving window, worth reading day by day rather than from the average.

Centro 22 pollen through the year
The Centro 22 pollen year runs in chapters, set by the Mediterranean pattern and the Italy calendar. Trees come first: cypress opens the year in winter, hazel and alder follow early, and olive carries the spring peak from April into May. Grasses take the middle of the year: grasses build from spring and peak from April into June, earlier in the south. Weeds close it out: weeds — pellitory through the warm months and ragweed in late summer where it has spread — close a long season that can run into November.
No Italy allergy season guide is published yet, so this page does not single out signature pollens for Centro 22 — the calendar above is the Mediterranean regional pattern, and the plant detail on this page names what today’s feed actually records.
November in Centro 22 sits inside the weed chapter of the Italy year, in its closing weeks — the part of the calendar today’s readings should be judged against. Between them, the three chapters cover 10 months of the Italy year, January to November — a long season by national standards, with only a short quiet gap. No Italy allergy season guide is published yet — this calendar follows the Mediterranean regional pattern. See Centro 22 pollen count rankings and Centro 22 on the pollen heatmap.
How to read this index
Pollen Atlas reports the Centro 22 pollen count on a Total Pollen Index from 0 to 100, built from separate tree, grass and weed readings. The total is a summary, not an average of the three: a single strong category can lift it, and three quiet categories can hold it down even in a month when Centro 22, Italy pollen is usually more active. Index values are a modelled pollen risk index computed by Pollen Atlas from open weather, vegetation and phenology data, calibrated against CDC/NAB season data, with plant detail by the Google Pollen API. The index is a modelled 0–100 scale, not a measured count, and figures update through the day, so a morning and an evening visit to this page can legitimately show different numbers.
